I'm using Ubuntu 13.04 (Raring)

I've installed CompizConfig Settings Manager (CCSM) and wanted to enable the wobbling window effect. This disabled some other things and suddenly I didn't have window borders any more...
Following various instructions I found at Google, I've tried the following steps:

1. Go to CCSM Preferences / Reset to defaults

This disabled all plugins and effects (including Unity) so I didn't get any further...

2. executing dconf reset -f /org/compiz and rebooting

This brought borders back, but still don't have close/mini/maxi buttons, can't resize or move windows. And the top left entries of the menu bar vanished (Logout, battery, volume...) so I have to shutdown my computer via a terminal...

Edit:

3. Following the instructions from the first answer.

This brought my menu bar applets back...
dpkg-reconfigure didn't seem to work. Result of this command:

Is there any possibility to reset the settings like they were after installing Ubuntu?

Edit 2:

Just noticed that the title bar of windows isn't missing; It's just hidden under the menu bar. So the buttons are only hidden, too.

Edit 3: PROBLEM SOLVED

Started CCSM, went to window management and checked scale windows and move windows... After a re-login everything was fine.
